The former Brazilian leader has been arrested after authorities concluded he posed a serious risk of fleeing while under home confinement.
The ex-president was sentenced of planning a military coup in the ninth month and handed more than 27 years in prison, but he remained under confinement pending legal challenges.
Top Judicial Official Justice Moraes said the move to detain the septuagenarian politician was a safety action after "new facts" emerged.
This involved trying to remove his tracking device and a call for a supporters' gathering that could facilitate a possible escape.
Judicial Records Show Flight Fears
In a filing authorising the detention, the magistrate said data from the centre monitoring the former president's confinement suggested the one-time head of state's "intention to break the electronic ankle bracelet to secure accomplishment in his getaway".
This, it said, would be assisted by the chaos caused by the demonstration called by his offspring.
His child, Flávio Bolsonaro, who holds office as a congressional representative, called for a gathering of his supporters near Bolsonaro's home to take place on Saturday night.
The senator wrote on online platforms on the previous day: "Are you going to fight for your nation, or see it all from your phone there on your sofa? I call on you to struggle with us."
He said the gathering would be so supporters could seek divine intervention for his health and for the return of democracy in our nation."
Foreign Shelter Risks
Part of the magistrate's ruling was the potential of Bolsonaro's "relocation to diplomatic missions near the residence, considering that the inquiries revealed a background of arranging to seek refuge through a embassy office", a declaration said.
The legal document underscores that the United States embassy in the capital, Brasilia, is positioned around 8 miles from his dwelling.
International Reactions
The former president's legal troubles have generated frustration from fellow populist conservative United States President Donald Trump, causing him to enact a half-rate duty on Brazilian product imports.
He is being held in a Federal Police station in Brazil's capital city and will experience a imprisonment assessment on Sunday.
Recent Legal Requests
It was only on last Friday that the his legal team asked the Supreme Court to permit him to complete his entire prison term under house arrest, with electronic monitoring.
They also requested that the former president be authorized to leave his home for healthcare, saying he needed regular treatment for pulmonary infections and other ailments.
Background on Conviction
Bolsonaro was determined responsible of heading a conspiracy aimed at keeping him in power after he was defeated in the national vote to his ideological adversary, Lula.
Top judicial officials said that he knew of a plot which involved plans to assassinate the current president and his running partner, Geraldo Alckmin, and to arrest and execute the presiding judge - the top judicial official who has been overseeing Bolsonaro's trial.
The conspiracy was prevented because it didn't receive the backing of the military leaders. Lula was took office without incident on 1 January 2023.
But a seven days after, on the eighth of January, numerous his backers invaded and destroyed official structures in the national capital, the capital city.
The police intervened and around approximately 1,500 persons were detained.
The justices found that the rioters had been encouraged by the former president whose scheme, they said, was for the national armed forces to take action, restore order and reinstate his authority.
At the time, Bolsonaro's lawyers called the 27 years and three months sentence unreasonably severe".
He was also barred from seeking elected position until twenty-sixty - eight years later after the conclusion of his imprisonment.
The former president called the court case a "witch hunt and said it was aimed at blocking him running in the 2026 national vote.
